Their bumper car game is basically this. Also, it would be beneath them to make a game like that. While it does seem they are no longer producing browser games, at most they would only parody games such as Mario, yet attempt to implement original gameplay mechanics and such.

I found a sort of glitch for speed running in the Bonus stage. IWeh by the cloudy-spike guys, if you die you have that recovery time. If you run into the spikes and through the waterfall you can bypass the first block all together. Doesn't add much, but it's something.
